Dahlia plant named ‘Baldadenapr’

ABSTRACT

A new and distinct cultivar of Dahlia plant named ‘Baldadenapr’, characterized by its double-type, yellow-orange colored inflorescences, dark green-colored foliage, and moderately vigorous, upright growth habit, is disclosed.

Latin name of genus and species of plant claimed: Dahlia variabilis.

Variety denomination: ‘Baldadenapr’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Dahliaplant botanically known as Dahlia variabilis and hereinafter referred toby the cultivar name ‘Baldadenapr’.

The new cultivar originated in a controlled breeding program in inOdense, Denmark during July 2016. The objective of the breeding programwas the development of Dahlia cultivars that are freely flowering withlarge inflorescences, mid-season flower timing, and a moderatelyvigorous, upright growth habit.

The new Dahlia cultivar is the result of open pollination. The female(seed) parent of the new cultivar is the proprietary Dahlia variabilisbreeding selection coded 17-497, not patented, characterized by itssemi-double, medium bronze-colored inflorescences, medium green-coloredfoliage, and moderately vigorous, mounded growth habit. The male(pollen) parent of the new cultivar is unknown. The new cultivar wasdiscovered as a single flowering plant within the progeny of the abovestated open pollination during July 2017 in a controlled environment inin Odense, Denmark.

Asexual reproduction of the new cultivar by terminal stem cuttings sinceJuly 2017 in in Odense, Denmark, Hem, The Netherlands and Andijk, TheNetherlands has demonstrated that the new cultivar reproducestrue-to-type with all the characteristics, as herein described, firmlyfixed and retained through successive generations of such asexualpropagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedlyobserved and can be used to distinguish ‘Baldadenapr’ as a new anddistinct cultivar of Dahlia plant:

-   -   1. Double-type, yellow-orange colored inflorescences;    -   2. Dark green-colored foliage; and    -   3. Moderately vigorous, upright growth habit.

Plants of the new cultivar differ from plants of the female parentprimarily in having more ray florets per inflorescence and ayellow-orange colored inflorescence that is different from thebronze-colored inflorescence of the female parent.

Of the many commercially available Dahlia cultivars, the most similar incomparison to the new cultivar is DALAYA Yellow+Red Eye ‘KLEDH13033’,U.S. Plant Pat. No. 26,741. However, in side-by-side comparison, plantsof the new cultivar differ from plants of ‘KLEDH13033’ in at least thefollowing characteristics:

-   -   1. Plants of the new cultivar have larger diameter        inflorescences than plants of ‘KLEDH13033’;    -   2. Plants of the new cultivar have more ray florets per        inflorescence than plants of ‘KLEDH13033’; and    -   3. Plants of the new cultivar have a ray floret color that is        yellow-orange and different from the yellow and reddish-orange        color of plants of ‘KLEDH13033’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonablypossible to make the same in color illustrations of this type, typicalflower and foliage characteristics of the new cultivar. Colors in thephotographs differ slightly from the color values cited in the detaileddescription, which accurately describes the colors of ‘Baldadenapr’. The4-month-old plants were grown in 6.5-inch pots for 10 weeks in aglass-covered greenhouse in Hem, The Netherlands. Plants were given onepinch before transplant.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmentalconditions to date. Accordingly, it is possible that the phenotype mayvary somewhat with variations in the environment, such as temperature,light intensity, and day length, without, however, any variance ingenotype.

The chart used in the identification of colors described herein is TheR.H.S. Colour Chart of The Royal Horticultural Society, London, England,2015 edition, except where general color terms of ordinary significanceare used. The color values were determined in February 2022 undernatural light conditions in Boskoop, The Netherlands.

The following descriptions and measurements describe 4-month-old plantsproduced from cuttings from stock plants and grown in a glass-coveredgreenhouse under conditions comparable to those used in commercialpractice. The plants were grown in Hem, The Netherlands in 6.5-inch potsfor 10 weeks utilizing a soilless growth medium. Plants were given onepinch before transplant. Greenhouse temperatures were maintained atapproximately 61° F. to 72° F. (16° C. to 22° C.) during the day andapproximately 57° F. to 61° F. (14° C. to 16° C.) during the night.Supplemental lighting was used. Measurements and numerical valuesrepresent averages of typical plants.
